O&O Defrag optimizes your hard disk and effectively and securely packs file fragments back together. O&O Defrag 11 includes an array of functions that a really good defragmentation software should offer, ranging from a fully automated defragmentation function to an expert settings option. Differences to previous versions We have expanded the range of functions of the new O&O Defrag 11 to make it even easier to use. For the first time, it is possible to defragment single folders or files over the context menu besides the usual hard disks and partitions. Furthermore, we have developed a background monitoring function, which automatically protects your computer against strong fragmentation without you as a user having to get involved. The new and sophisticated file status view shows you the quantity and the fragmentation level of the most extensively affected files. Also, the already familiar block view has been enhanced with detailed information. Thus, you will receive an overview with O&O Defrag 11, of where the individual fragmented parts of the files are to be found on the hard disk. Maximum efficiency thanks to new technology Fragmentation is the main reason for an extensive performance loss under Windows. Since hard disks tend to be the slowest components of a computer, it is imperative that their performance is optimized. Newly developed technologies within O&O Defrag 11 allow for an even better adjustment to Windows Vista and a better processing of especially big file systems (several million files) while still using the least amount of working memory. Thanks to O&O Defrag 11, many files can be read and written much faster and you can be sure that your hard disk is continuously performing at its peak.
